The Naarva S35C is a lightweight and compact stroke harvester designed for easy installation and operation – with no modifications needed to the base machine. This harvester is built for versatile use. Its robust construction is optimized for high feed force. No cables are needed on the boom, as the unit features a fully rotatable rotator. Its grapple-style blades and arms allow for loading, and the hydraulic tilt is adjustable.

The Easiest Harvester Head on the Market

The grapple operates with bi-directional hydraulics. It has only two hoses and requires just 50–70 l/min oil flow. Installation with a fully rotatable rotator. Features reliable wireless control and Bluetooth measuring device. Only three solenoid valves and an innovative sequence valve block.

The New Saw on the Naarva S35C Model

Specifically designed for the Naarva S35C. Efficient sawing performance is achieved with low oil flow. Chain lubrication to the bar is handled without moving hoses or pipes, and leakage oil return is done with an ejector, no separate hose needed. A chain oil reservoir is available as an optional accessory. Harvester bar length is 59 cm and maximum cutting diameter is Ø 42 cm.

User-Friendly Hydraulics

The stroke harvester’s hydraulics are divided into two blocks, making maintenance easier. Electric and pressure control valves for tilt and feed are located in the tilt arm. The unit has three solenoid valves and only one control button, making the harvester very comfortable to use. There are no electronic pressure controls. Force and movement synchronization is reliably managed by cartridge valves.
